[0037] This implementation utilizes the interpretation of the invention claims. The protection scope of the present invention is not limited to the structure described below. Those skilled in the art will know that any structural changes made within the technical solution of the present invention that are different from the following structures belong to the protection scope of the present invention.

[0038] As shown in FIG1 , an integrated grinding head with an angled strip is used for a decorative glass edge grinding machine. The grinding head swing seat assembly 1310 is connected to the integrated grinding head 1320 through an arc-shaped slider assembly 1321. The motor seat assembly 1330 is fixed to the top of the integrated grinding head 1320 by screws. The integrated bracket assembly 1350 is fixed to the integrated grinding head 1320 by a bracket pin 1353. The knife-beating cylinder assembly 1360 is fixed to the top of the integrated grinding head 1320 by screws to achieve functional integration.

[0039] like Figure 2-1 , Figure 2-2 As shown, the upper arc-shaped guide rail 1311-2 and the lower arc-shaped guide rail 1311-3 are respectively installed in front of the grinding head swing plate 1311-1, and play the role of the wire harness arc-shaped slider assembly 1321 swinging within a set arc.

[0040] like Figure 3 As shown, the rotation axis at the upper end of the grinding head swing plate 1311 - 1 has a certain angle with the sliding surface, and is a non-parallel structure.

[0041] like Figure 4As shown, the slide locking mechanism 1313 is installed on the back of the grinding head swing plate 1311-1. Through the extension and retraction of the cylinder piston, the locking plate 1313-1 is driven to rise and fall with the half shaft 1313-4 as the central axis, thereby tightening and loosening the arc-shaped slider assembly 1321.

[0042] like Figure 5 , 12 As shown, the integrated grinding head 1320 is formed by installing the synthetic grinding head seat assembly 1323 on the arc-shaped slider assembly 1321. The grinding head spindle assembly 1324, the worm assembly 1326, the worm wheel assembly 1325, and the spindle locking assembly 1322 are all installed in the synthetic grinding head seat assembly 1323 to form an assembly that can swing with the arc-shaped slider assembly 1321 to complete the functions of the grinding head spindle assembly 1324 to deflect, rotate, compensate, lock, and relax.

[0043] like Figure 6 2, the arc-shaped slider assembly 1321 is connected to the slide locking mechanism 1313 in FIG. 2 through a locking rod 1321-3 fixed in the hole of the arc-shaped slider 1321-1. Figure 6 The spherical pad 1321-4 in the middle is pressed on the locking plate 1313-1, and as the locking plate 1313-1 rises and falls, the arc-shaped slider assembly 1321 is tightened and loosened, thereby tightening and loosening the integrated grinding head 1320. The arc-shaped rack 1321-2 is installed on the top of the arc-shaped slider 1321-1, and is tightened and loosened by Figure 2-2 The swing angle gear 1312-3 drives the arc-shaped rack 1321-2 to swing left and right, thereby driving the integrated grinding head 1320 to swing in the slideway composed of the upper arc-shaped guide rail 1311-2 and the lower arc-shaped guide rail 1311-3.

[0044] like Figure 7 As shown, the composite grinding head seat assembly 1323: its cylinder head 1323-2, worm seat 1323-4, worm shaft cover 1323-6, guide bolt shaft 1323-8, are all installed on the grinding head seat 1323-1.

[0045] like Figure 8 As shown, the grinding head spindle assembly 1324: the lifting bearing 1324-5 is installed on the spindle spline sleeve 1324-4, and the spindle spline sleeve 1324-4 can slide up and down on the spindle 1324-2 to ensure that the relative height between the spindle spline sleeve 1324-4 and the spindle motor does not change. The front flange 1324-3 and the rear flange 1324-7 are installed at both ends of the spindle sleeve 1324-1 to fix the spindle 1324-2, and the tool handle 1324-6 is installed at the lower end of the spindle 1324-2.

[0046] Fig. 9As shown, the worm assembly 1326: the worm bearing 1326-5 and the worm synchronous wheel 1326-4 are installed on the worm 1326-1. In this way, the worm assembly 1326 can be installed Figure 7 The worm seat 1323-4 is the same.

[0047] like Fig.10 As shown, the worm gear assembly 1325: the horizontal bearing 1325-2 and the worm gear 1325-5 are installed on the horizontal gear 1325-1. Fig. 9 The worm 1326-1 meshes with the worm gear to rotate the worm gear assembly 1325. The horizontal gear 1325-1 and Figure 8 The spur teeth of the main shaft sleeve 1324-1 mesh with each other to play the role of raising and lowering the grinding head main shaft assembly 1324.

[0048] As shown in FIG11 , the spindle locking assembly 1322: the locking rod 1322-4 is installed on the locking cylinder 1322-1 and the piston rod, and the two clamping blocks 1322-3 are connected in series on the locking rod 1322-4. Through the contraction of the piston of the locking cylinder 1322-1, the distance between the two clamping blocks 1322-3 is shortened, and the semi-arc surface of the clamping block 1322-3 is connected to the piston rod. Figure 8 Main shaft sleeve 1324-1 outer circle, Figure 7 The inner hole of the grinding head seat 1323-1 forms a wedge angle, thereby locking the main shaft sleeve 1324-1 and the grinding head seat 1323-1 into a whole.

[0049] like Fig.12 As shown in 13, the integrated bracket is a combination: the bracket assembly 1350 is installed on the integrated grinding head 1320, and the cylinder pulls the rotating Fig.13 The bracket shaft 1353 rotates, and when the cylinder piston extends, the bracket arm 1351 moves down to the supporting position, and the supporting wheel 1355 is in Figure 3 The grinding head swing plate 1311-1 is on the rotation axis line and is at the same time Figure 6 On the axis of the center of the arc-shaped slider 1321 - 1 , the bracket locking assembly 1327 locks the bracket assembly 1350 on the integrated grinding head 1320 .

When the bracket arm 1351 rotates down to the lifting position, the piston 1327-2 moves downward, driving the locking tongue 1327-4 downward, and the inclined surface on the locking tongue 1327-4 fits with the inclined surface on the bracket arm 1351, locking the bracket arm 1351, and keeping the relative position of the workpiece and the grinding wheel unchanged.

At present, the centering of the grinding head is achieved by the algorithm of the program. The cost is high, the three-axis precision control requires high manufacturing difficulty and complexity. This solution simplifies the difficulty and cost of mechanical structure and program development.
